Product details
Overview
TLV2474CPWP from Texas Instruments is a quad rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, 250μV typical input offset voltage, and operates from 2.7V to 6V - enabling precision sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2474CPWP datasheet, TLV2474CPWP pinout, TLV2474CPWP application, or TLV2474CPWP equivalent, this page provides verified technical context, TSSOP-14 package mapping, rail-to-rail I/O behavior under load, shutdown current specs (1000nA/ch @ 5V), and validated alternatives for low-voltage data acquisition designs.
Technical Context
The TLV2474CPWP implements a CMOS input stage with 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), enabling full-swing operation in 3V systems. Its output stage supports ±35mA sourcing/sinking while maintaining 180mV rail clearance under 10mA load - resolving key limitations of legacy micropower op-amps.
It features an integrated shutdown control (SHDN) that places outputs in high-impedance state and reduces supply current to 1000nA per channel at 5V. The device is fully specified across –40°C to +125°C and exhibits 68° phase margin into 1000pF capacitive loads with 10kΩ series resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or closed-loop amplification up to ~200kHz with 10x phase margin. |
| Supply Current per Channel | 600μA @ 5V - supports battery-powered operation with >1-year runtime on coin-cell sources in duty-cycled systems. |
| Output Drive Capability | ±35mA @ 500mV from rail - drives 10kΩ loads to full rail while delivering >20mA into 100Ω loads without clipping. |
| Input Offset Voltage | 250μV (typ) - ensures <1mV total error in 12-bit ADC front-ends with gain ≤ 4, minimizing calibration overhead. |
| Rail-to-Rail I/O | Inputs swing 0V to VDD; outputs swing within 180mV of rails @ 10mA - maximizes dynamic range in 3V/5V single-supply data loggers. |
| Shutdown Current | 1000nA/ch @ 5V - reduces system standby power by >99.8% vs active mode, critical for always-on sensor nodes. |
| Common-Mode Input Range | 0V to VDD - accepts ground-referenced signals directly without level-shifting in single-supply configurations. |
Pinout & Package
TSSOP-14 (PWP) package: 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad optional, RoHS-compliant, rated for industrial temperature range (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | Output (OUT1–OUT4) | Amplified buffered output; high-impedance during SHDN assertion. |
| 2, 6, 9, 13 | Inverting Input (IN−1–IN−4) | Differential input node; CMOS input draws only 2.5pA bias current. |
| 3, 7, 10, 14 | Non-Inverting Input (IN+1–IN+4) | Differential input node; supports 0V to VDD common-mode range. |
| 4 | VDD | Positive supply rail (2.7V–6V); decoupling capacitor required at pin. |
| 11 | GND | Analog ground reference; separate return path recommended for noise-sensitive layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Same electrical specs; SOIC-14 package (8.65mm × 3.91mm), no exposed pad, higher θJA (122.3°C/W). | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less suitable for thermally constrained layouts. | Select when board space allows larger footprint and thermal management uses copper pour instead of exposed pad. |
| OPA4340UA | Higher GBW (5.5MHz), lower noise (12nV/√Hz), but 750μA/ch supply current and no shutdown function. | Better for wideband sensor excitation or audio preamp roles; unsuitable where shutdown power gating is mandatory. | Choose when bandwidth >3MHz is required and system-level power budget permits 25% higher active current. |
Compared with TLV2474CPWP, TLV2474CDR offers identical performance in a larger SOIC package ideal for manual assembly, while OPA4340UA trades shutdown capability for higher speed and lower noise - making TLV2474CPWP optimal for thermally dense, battery-gated, rail-to-rail precision applications.

FAQ
What is the maximum capacitive load the TLV2474CPWP can drive stably?
The TLV2474CPWP maintains ≥61° phase margin into 1000pF loads when configured with 10kΩ series resistance (RNULL) at the output. Driving >10pF directly causes peaking or oscillation; TI recommends inserting 20–100Ω RNULL in series with capacitive loads exceeding 10pF. This design rule ensures stability in ADC reference buffers and active filters using TLV2474CPWP.
Does the TLV2474CPWP have internal ESD protection, and what is its rating?
Yes, the TLV2474CPWP includes internal ESD protection diodes on all pins rated to ±2kV HBM (Human Body Model) per JEDEC JS-001. Texas Instruments explicitly warns that improper handling may cause latent damage, especially to the high-impedance CMOS inputs. Always use grounded wrist straps and ESD-safe workstations when assembling TLV2474CPWP into production boards.
Can the TLV2474CPWP operate from a 2.5V supply?
No - the absolute minimum supply voltage for TLV2474CPWP is 2.7V per the datasheet's Recommended Operating Conditions table. Operation below 2.7V risks undefined behavior, including failure to achieve rail-to-rail output swing, increased input offset voltage, and potential shutdown circuit malfunction. For 2.5V systems, consider the TLV2464 or OPA4316 as alternatives.
How does the shutdown function behave on the TLV2474CPWP?
The TLV2474CPWP has no dedicated shutdown pin; it belongs to the non-shutdown variant of the TLV247x family (per Family Package Table). Unlike TLV2470/3/5, TLV2474CPWP lacks SHDN terminals - all four amplifiers remain active whenever VDD is applied. This simplifies layout but eliminates per-channel power gating capability present in other family members.
What is the thermal resistance (θJA) of the TLV2474CPWP in TSSOP-14 package?
The TLV2474CPWP in TSSOP-14 (PWP) package has a junction-to-ambient thermal resistance (θJA) of 30.7°C/W, measured on a standard 2-layer JEDEC test board with 1-inch² copper area. With proper PCB thermal vias under the exposed pad (if used), actual θJA can improve to ≤25°C/W - enabling continuous operation at 6V/±35mA output without exceeding 125°C junction temperature.
